That looks to me like an issue with your hardware, I would suggest giving your library a quick once over and if nothing obvious is spotted log a call with the vendor to investigate the problem.

Hi,

I can see an error at scsidev@10.2.0, but I can't see the same device at inquire exit (it could be an erroneous configuration at linux servers, maybe a reboot or reconfiguration are needed) Obviously, DataDomain can handle this device by itself.

I hope these can be helpful.

Regards

Claudio

I could not reboot at this time , but regard configuration .....can you explain if there is certain details for reconfiguration of the Tape @ linux OS. BR

David_Hampson_90e289 · Answer

Is that your full inquire output?  The media changer (virtual jukebox) does not seem to be listed although it does look like you may have cut off the inquire output.

hantashhantash · Answer

actually there is no auto changer on this linux , it is only one drive for this remote storage node and the auto channger in on windows networker server I only run inquire | grep tape regards

David_Hampson_90e289 · Answer

Okay, I understand.  So when you try mounting tapes in any other drives from Networker they mount without problem, and this device can be mounted from the virtual library console, is that right?

hantashhantash · Answer

you are exactly right 100 % ,

all other nodes works are windows and these non working two nodes are linux , all services nsrmmd are working fine

I see the in the deamon.raw for the linux said that

cdi warning" pathuthrugg old St driver

any suggestions

tonyalbers · Answer

1. is networker running as root on the storage nodes?

2. What are the permissions for the devices (ls -l /dev/nst*)

3. can you use the tape drive from the OS (mt -f /dev/nst0 status and mt -f /dev/nst0 fsf3 ; mt -f /dev/nst0 rewoffl )

scsidev@3.3.0:IBM ULTRIUM-TD3 8711|Tape, /dev/sg11

Your virtual LTO3 has the incorrect drive path, it should be /dev/nst1, this device is using a path assigned by a SCSI generic driver which is not correct one o use for a tape device.
